With pre-filter and protective cover (without housing)
\nExplosion-proof valves are protective devices that remain open under normal conditions. This allows air to flow freely in both directions - in and out of the protected space. They are usually installed on vents or ducts in ventilation systems. Their main task is to protect the shelter spaces, structures against the pressure waves, both positive and negative, generated by the explosion.<\/p>\n

Technical specifications for explosion-proof valves:
\nResistance to back pressure: >900 kPa (9 bar)
\nMechanical shock resistance: >12 g
\nValues apply to version Y (safety valve only).
\nBVNO valves can be customised to suit individual needs, for example by fitting them with a body that connects to the duct, as well as flanges, pre-filters or quick connectors. In addition, such customisation makes it easier to integrate existing ventilation systems. This allows BVNO valves to meet different requirements, both in terms of installation and specific operating conditions.<\/p>","protected":false},"excerpt":{"rendered":"
